General Information

HEATER SYSTEM
All models use a Blend-Air type heater. Outside air enters the through the cowl opening and passes through a plenum chamber and the evaporator and then to the heater core. Air intake openings must be kept free of snow, ice and other obstructions for the system to pick up a sufficient volume of outside air. A temperature control door in the housing directs incoming air through and/or around the heater core. The amount of blend (heated, non-heated or cooled air) is determined by the setting of the temperature knob on the instrument panel. Direction of the blended air is controlled by the mode knob on the instrument panel.

The blower switch and resistor block controls the speed of the blower motor. This in turn controls the velocity of the air flow from the FLOOR (heater), DEFROST or PANEL outlets.

COOLING SYSTEM REQUIREMENTS
To maintain the performance level of the heating//air conditioning system, the engine cooling system must be properly maintained.

The use of a bug screen is not recommended. Any obstructions in front of the radiator or condenser can reduce the performance of the A/C and/or the engine cooling system.
